I thought namespaces were a pain to implement.
I have a question about "Validity constraint: Proper Declaration/PE
Nesting" [1] I understand that this is saying the following is violates
the VC:
Doc1.dtd
========
<!ENTITY % e "<!-- a ">
<!ENTITY % f "%e;comment -->">
Doc2.dtd
========
<!ENTITY % e "<!-- a ">
But what about this:
Doc3.dtd
========
<!ENTITY % e "<foo>">
<!ENTITY % f "%e;</foo>">
<!ENTITY g "%g;">
I think that it is legal but who knows anymore. As near as I can figure
it doesn't violate this VC because it is not a markup decl specifically.
Also, it is not a violation of "Validity constraint: Proper Group/PE
Nesting" [2]. I assume it is valid because of this text in 4.3.2 "An
internal general parsed entity is well-formed if its replacement text
matches the production labeled content. All internal parameter entities
are well-formed by definition."
Bonus questions: Which wins out: "Well-formedness constraint: In DTD"
[3] or "Not Recognized" [4]
